Hands down the best compressione tool on the mac. And close to perfection now with the 1.8 release, where the archives can be moved to the trash after being successfully extracted. My next feature would be the possibility to enqueue the files to extract.

Excellent application. First of all it may become a Mac version of WinRAR (thanks to supporting commandline RAR) and native support for creating 7ZIPs is excellent. Unlike Unarchiver it works fine with password-protected RARs and also lets you preview files before extracting. And finally, it works well as unarchiving tool even after expiration.
The best mac archiver I've seen so far.

this is by far the most intuitive and functionally efficient compression application on the mac platform. i just made the switch from pc to mac about a week ago, after trying upwards of half a dozen archiving programs i finally settled on this one and it has proved to be an invaluable addition to the collection of software i have amassed thus far.
